Choose flooring based on room usage, moisture exposure, and maintenance preferences. Compare materials for durability, water resistance, and long-term value. Consider maintenance requirements and replacement cycles when calculating true ownership costs over time.

Success requires proper planning and preparation regardless of DIY or professional installation. Avoid common mistakes by following manufacturer guidelines, allowing proper acclimation time, and addressing subfloor issues before installation. Keep extra material for future repairs and maintain consistent batch/lot numbers for color matching.

Frequently Asked Questions

Measure the length and width of each room in feet, then multiply them to get the square footage. For irregular shapes, break the room into rectangles, calculate each area separately, and add them together. Always add 5-15% extra for waste, cuts, and future repairs. Our calculator handles these calculations automatically and adjusts waste percentage based on your flooring type and installation pattern.
Standard waste percentages vary by material and installation pattern: Straight layout requires 5-10% extra (laminate, vinyl, hardwood), diagonal patterns need 10-15%, herringbone or chevron patterns require 15-20%, and tile typically needs 10-15% due to breakage. First-time DIY installers should add an extra 5% to these recommendations. Complex room shapes with many angles also require higher waste factors.
Installation costs vary significantly by material and region. Typical ranges include: Carpet $0.50-$2 per sq ft, Vinyl/LVT $1.50-$3 per sq ft, Laminate $2-$4 per sq ft, Hardwood $3-$8 per sq ft, and Tile $5-$15 per sq ft. Additional costs may include removing old flooring ($1-$3/sq ft), subfloor repair ($2-$5/sq ft), and moving furniture. Stairs typically cost 2-3 times more per square foot than flat surfaces.
A complete flooring project includes: Materials (flooring, underlayment, adhesive), installation labor, transition strips and moldings, removal and disposal of old flooring, subfloor preparation or repairs, and moving furniture. Optional costs might include moisture barriers, soundproofing underlayment, floor leveling compound, and baseboards or quarter round. Our calculator helps estimate these comprehensive costs based on your specific project requirements.
Measure the main room area first, then measure each closet, alcove, or nook separately. Add all areas together for the total square footage. For angled walls or bay windows, approximate the area by creating rectangles that encompass the space. Include all areas where flooring will be installed, but exclude permanent fixtures like kitchen islands or built-in cabinets. Always round up measurements to ensure adequate material.
Floating floors (common with laminate and luxury vinyl) click together and rest on underlayment without being attached to the subfloor, making them easier to install and remove. Glue-down installation adheres flooring directly to the subfloor, providing better stability and moisture resistance but requiring more skill and time. Nail-down installation is used primarily for solid hardwood. Each method has different material and labor costs reflected in our calculator.
Installation time depends on room size, flooring type, and complexity. Professional installers typically complete: 300-500 sq ft of vinyl or laminate per day, 200-300 sq ft of hardwood per day, 100-200 sq ft of tile per day. DIY installation usually takes 2-3 times longer. Preparation work like removing old flooring or leveling subfloors adds 1-2 days. Most whole-house projects take 3-7 days professionally or 2-3 weeks for DIY.
Underlayment requirements vary by flooring type: Laminate needs foam or cork underlayment (2-3mm) for cushioning and sound reduction. Luxury vinyl may require specific underlayment or none if it has attached padding. Hardwood uses rosin paper or synthetic underlayment as moisture barriers. Carpet requires padding (usually 7/16 to 1/2 inch thick). Tile needs cement backer board or uncoupling membrane. Choose underlayment based on subfloor type, moisture concerns, and sound requirements.
Stairs require special calculation: Measure each tread (horizontal part) and riser (vertical part) separately. Standard treads are about 10-11 inches deep and 36 inches wide. Each step typically needs 3-4 square feet of material including the riser. Add 20-30% waste for stairs due to precise cutting requirements. Don't forget stair nosing (the overlapping edge) which is sold separately. Professional installation is often recommended for stairs due to complexity.
Flooring lifespan varies considerably: Quality hardwood lasts 50-100+ years with refinishing every 10-15 years. Laminate typically lasts 15-25 years but cannot be refinished. Luxury vinyl plank (LVP) lasts 20-30 years with proper care. Tile can last 50-100 years if properly installed. Carpet needs replacement every 5-15 years depending on quality and traffic. Factors affecting durability include foot traffic, moisture exposure, maintenance, pet activity, and installation quality.
Yes, always order 1-2 extra boxes for future repairs. Flooring dye lots can vary between production runs, making exact color matching difficult later. Store extra planks in a climate-controlled area. Having matching material allows for seamless repairs if boards get damaged. This is especially important for discontinued styles or unique patterns. The small additional cost is worthwhile insurance for maintaining your floor's appearance over time.
Installation patterns significantly impact material requirements and waste: Straight/parallel installation is most efficient with 5-10% waste. Diagonal (45-degree) installation requires 10-15% extra material. Herringbone or chevron patterns need 15-20% additional material due to precision cuts. Random patterns need 10-12% extra. Brick/offset patterns require 8-10% waste. Complex patterns also increase installation time and labor costs. Our calculator adjusts material estimates based on your selected pattern.
